Purity:
≥ 90 % as determined by SDS-PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Bio-Activity:
Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human Galectin-9 at 2 μg/mL can bind Recombinant Human TIM-3 with a linear range of 5-15 μg/mL.
Measured by the ability of the immobilized protein to support the adhesion of Jurkat human acute T cell leukemia cells. When 8×10 4 cells/well are added to LGALS9 coated plates (5 μg/mL and 100 μL/well) in the ppresence of 10μg/ml PHA, approximately 70-80% cells will adhere specifically after 60 minutes at 37℃.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Recombinant Human Galectin-9/LGALS9 Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue.
Immobilized Recombinant Human Galectin 9 at 2μg/mL can bind Recombinant Human TIM-3 with a linear range of 5-15μg/mL.
